Can some help with Ayane's back attacks? Is there any easy way to do them? I keep messing up on them.

that depends on what your having troubles with :P

is it turning around if so use her diagonal back and up and P to jump away from your opponent and have your back facing then, provides easy use for back flip or the roll kick

if its attack its kinda hard to say unless u tell us what attack your trying to do

It is very easy. all you have to do is
PP6P while back is turned and press B to make it a power attack or
PP6PF7K It does more damage idf you do not hit a wall.
