Warfare would be just like normal crusades - full on attacks on empires to convert or die. Crusader states would also most likely arise, like the principality of antioch and the kingdom of jerusalem, except with different races in charge.

In terms of battles, there would most likely be planetary assaults as well as naval battles.
