I don't believe they're known at this time.
The wiki has collated a list of executable abilities for dragon knights, sorcerers and templars from one of the earlier hands on events.

From an article just published a few hours ago. Not clear if he's just categorizing the kinds of abilities that Templars get or if this is how their skill trees are divided up but it would make sense.

Along with these points, level ups grant the ability to learn new skills in several class trees depending on your class. The Templar we played during our hands-on had access to a variety of physical attacks, magical assaults, and healing spells.
