I haven't really decided on a full list of powers that Gryphine mages have, but they can create energy balls and cast simple spells. Gryphine mages are usually seen with an energy ball, the colour differs between Gryphines however the colour does tend to run in the family. For example, Perein's energy balls are blue and so are Acquila's.
For elementals, they would have control over their element, so for example, Proteus is of the element electricity so he can control electricity and cause lightning to strike, etc. They would usually be drawn with their element, so a fire elemental might have fire burning on its back. There aren't any specific required traits for an elemental.
I guess I should get a species page put together shouldn't I...
