My SO is vegan so I deal with this on a daily basis...
Get the Ener-G egg replacer at whole foods or similar health-food store. Use Earth Balance spread for butter. It also comes in sticks. Use the recipes you always have, but replace...replace...replace.
My experience is that the cakes are a bit more dense. Because of that, I use gluten free baking mixes, which tend to be lighter. Pamela's is a good one a can recommend and I love the vegan pancakes I make with it.
