Let's assume that whatever it is you want to do with each faction is possible, what are your plans for the following:
Mages
Templars
Seekers
The Chantry
Orlesian Loyalist (Celene's Faction)
Orlesian Patriots (Gaspard's Faction)
Elven Rebels
Dalish Elves
Grey Wardens
I'll throw in these as well, but we don't know of any conflict happening with them:
Tevinter
Qunari
Fereldan
Antivan Crow's
Let me know if I've missed anyone and share your plans 
This is outcome I'd like to have for different groups and areas ^^ In the game I'd like ally myself with more neutral templars and mages, also elven rebels and dalish more likely.
Mages -> Schooling system.
Templars -> Guards and police force to mages.
The Chantry -> Seperate religion from state.
Elven rebels -> Help them, equal rights for Elves.
Dalish Elves -> Let them be.
Grey Wardens -> Let them be.
Tevinter -> Destroy the current system.
Qunari -> Exterminate Qun.
Fereldan -> Alliance.
Antivan Crow's -> Let them be.
Mages: Independence from chantry, circles as professional training centres for mages
Templars: Police force to deal with apostates and those that breach rules
Chantry: Try and separate Chantry from political and military power.
Elven Rebels: Equal opportunties for them
Orlesian Loyalist (Celene's Faction) - Political Marriage to Gaspard
Orlesian Patriots (Gaspard's Faction) - Political Marriage to Celene
Dalish: Leave them be
Grey Wardens: Ensure they remain neutral
Tevinter: Let them be
Qunari: do everything possible to undermine them
Ferelden: Leave them be
Antivan Crows: Leave them be
Probably a different outcome for each character I play, but my main character, as always, is going to be pro-mage.
For my first run:
Mages > Whatever
Templars > Whatever
Seekers > Whatever
The Chantry > Whatever
Orlesian Loyalist (Celene's Faction) > Back on power
Orlesian Patriots (Gaspard's Faction) > Exectute
Elven Rebels > Reclaim the Dales and unite all elfs
Dalish Elves > Reclaim the Dales and unite all elfs
Grey Wardens > Whatever
And the second:
Mages > Absolute freedom
Templars > Extermination
Seekers > Extermination
The Chantry> Extermination
Orlesian Loyalist (Celene's Faction) > Stand aside or die
Orlesian Patriots (Gaspard's Faction) > Stand aside or die
Elven Rebels > Help me and I'll help you
Dalish Elves > Help me and I'll help you
Grey Wardens > Who ?
Mages: Exterminate those who resist, welcome those willing to live under templar rule or as soldiers of the inquisiton
Templars/Chantry: Combine our organizations so we are 3 divisions of the same organization
Elven Rebels: Surpress them
Orlesian Loyalists: Help
Orlesian Patriots: Destroy
Dalish: Destroy
Grey Wardens: Alliance
Tevinter: With the help of the templars destroy
Qurani: Wipe out
Fereldan: Alliance
Mages - Imprison or vanquish
Templars - Vindicate and Uplift
Chantry - Establish as the only power in Thedas
Qunari - Lend aid against Magisters
Tevinter - Send to Belize
Elves - Cut off their ears and feed them to our Mabari
Red Templars - Establish as Thedas' premier fighting force
Mages=Returned to more balanced Circle (If possible, otherwise destroyed)
Templars= Returned to more balanced Ciricle (If possible, otherwise aided)
Seekers=meh
The Chantry=Restored to proper place
Orlesian Loyalist (Celene's Faction)=Eliminated
Orlesian Patriots (Gaspard's Faction)=Given Throne
Elven Rebels=Don't care.
Dalish Elves=Don't care
Grey Wardens=Protected and aided
Tevinter=Treated with respect
Qunari=Ready to oppose if need be
Fereldan=Restored and expanded
Antivan Crow's=Destroyed if possible (The Crows are wild cards the deck that is Thedas does not need)
What I do in every RPG...
If You Can't Join 'Em, Kill 'Em. 
mages: independent from chantry allowed to live in communities
Templars: police force for mages, but not on station in the communities... (kind of like fbi, only called in for crimes involving magic)
Chantry: severely reduce its power, no more exalted marches
Orlesian loyalists: Kill Celene
Orlesian Patriots: Kill Gasspard and name someone new emperor/empress
city elves: help them, but at the same time stop their rebellion
Dalish: leave them
Qunari: tevinter's problem unless they invade, then destroy them
Ferelden: leave them
GW: leave them unless they pose a threat
Crows: leave them
Red templars: Destroy
Venatori: Destroy
Ideally I'd have them all ally with and serve troops to the Inquisition, but seeing as how presumably some may be exclusive I'll make a game-time decision. The only clearly exclusive faction I can think of right now may be templars vs. mages, in which case I'd favour mages.
Mages - I support their separation from the Chantry with the circles converted into schooling systems, like some others have said.
Templars - Act as a police force in case of magical crimes.
Seekers - Merged with templars, no real need for the separation.
The Chantry - They're one religion and they do not need military force. Their influence over the world needs to be marginalized.
Orlesian Loyalist (Celene's Faction) - I'll most likely support her, if she'll work with the elves.
Orlesian Patriots (Gaspard's Faction) - He'll likely end up dead.
Elven Rebels - I will support them towards as much equality as I'm able.
Dalish Elves - I hope they can be convinced to work with the city elves. Otherwise, they're on their own.
Grey Wardens - They should be allowed to continue in case of another blight. Not sure what their controversy is, so we'll have to wait and see.
Tevinter - Slavery needs to be abolished, but I can't see that happening this game.
Qunari - I will act against them in any way possible.
Fereldan - They've seemed fairly moderate, so I can't see a reason to oppose them.
Antivan Crow's - I don't have a strong opinion of them. They likely wont have a strong influence on this game.
Depends what sort of influence I will have in the game as the Inquisitor, whether I will actually have any impact in centralizing political, economical and military decisions across Thedas. Also depends on how coming events will occur and what parties will be involved and how much involvement they ultimately will have. Hopefully options like these will be present since I do have some kind of long time goal.
"Burn them all." --Aerys Targaryen
I am yet to decide on what to do with The Mages/Templars. It depends on what exactly they want, if they want to simply be rid of the Templars then I can accept that, if they want to remove the circle system and live among the rest of the populace I will crush them and throw them back in their towers... Personally I'd prefer A Loc Muinne situation like in the Witcher 2, give them their own isolated city to govern over and police themselves, but make it a protectorate of a more powerful nation like Orlais.
As to the Civil War, I will side with Celene get her the Imperial throne and crush Gaspard.
everything else Im yet to decide
I need to know how each faction operates at this point (goals, resources, leader characteristics, etc.) before I can decide each's fate.
Mages-kill them all
Templars-remove and replace or change so they could be more efficient.
Seekers- remove/destroy or just merge with new-anti mages as they never were more.
Chantry-destroy or kick out from political power and separate from dealing with mages also use them as tool to spread hate toward mages so my anti-mage polices could be more effective.
Orlais-burn it or at least weaken it of course after they will help me i can send them gladly to die fighting demons.
Elves- don't know now if they can help i will take them then as i said many times they would be used as cheap workers like miners.
Tevinter-Destroy but not now in future let them fight with qunari so they could weaken each other.
Qunari-as above let them fight with tev and prepare by improving technology to fight with them.
Crows-Destroy
Ferelden-Try improve and reform some things...

Would love to hear your opinions about them.
They will all bend the knee or I will destroy them.
Mages - blow off Adrian's head
Templars - make them serve the Inquisition
Seekers - clean house with their leadership
The Chantry - they are pretty good
Orlesian Loyalist (Celene's Faction) - not helping them
Orlesian Patriots (Gaspard's Faction) - maybe helping them
Elven Rebels - smash every damn mirror
Dalish Elves - need to see more about their involvment before I make a choice
Grey Wardens - based on trailer, probably gonna have to attack them
Antivan Crows - make them serve me
