Not include egg in baked goods?
My friend is vegan and cooked muffins with all the normal ingredients (switching milk for soy milk) and just left out egg- she did not use any type of substitute. Her muffins turned out great and very moist! Why are eggs included in baked goods and pancakes as it didn't seem to effect her recipe- she did not even include any source of fat! She said that eggs make the baked goods tougher actually.

Muffins are actually a good thing to make egg free as there is usually only one in the entire recipe and given their compact size, they seem to add less to structure.
