If you have a food processor, you can make your own bread crumbs from whole wheat bread. Just tear up the bread and process it until it is crumbs. This is a great use for stale bread. I make a bunch and keep it in the freezer.
Oatmeal is also a great binding agent and often used instead of bread crumbs in meatloaf, meatballs, etc. I don't know why it wouldn't also work in falafel. I'd bet you could also use oat bran, which is a finer grain than oatmeal but just as healthy.
