Templar are worthless in battlefield conditions. while effective against mages they also have to deal with tevinter soldiers who can easily bog down the templar order . any sane commander would enmass target the templars with non magical artillery and arrow barrages al the while shielding his mages with troops. i also doubt that the templars are an effective fighting force against regular soldiers. templars operate in small groups and this will not fit on the battlefield where formation is essential.
Most likely the circle of mages had a far greater impact (confirmed in asunder) on the battlefield . Defeating several exalted marches and defeating the qunari on their home soil alone means that they are the most powerful land army. however qunuari have the advantage at sea.
Regarding the effectivness of templars against magic.
Seems to me that Templars are simply able to cast certain spells from the spirit school, by using Lyrium: A veriaty of dispel types, and a weaker version of "mana clash".
(that does raise the question what exactly is the difference in this regard between the schools, shouldn't a Templar be able to get limited access to all types of magic in the same way? Seems logical to me.)
And if so, their presence is not an automatic win against magic users, but rather it depends on the willpower and skill of both the mage and the Templar.
The advantage Templars will have, probably lies in their ability to use multiple mediocre "casters" as a way to defeat one Mage. (assuming of course that at this point the mage does not resort to blood-magic to level the playing field)
