I was searching for some chia cupcake recipes and not having much luck. One of the top results was actually for a Vegan Chocolate Cupcake, but I did not see chia listed in the ingredients.
Well, I found out why this site ranked for chia cupcakes. In the comments, one poster suggested that cia seeds could be substituted for eggs. According to the comment, 1 egg= 1 TBSP chia seeds+ 3 TBSP water. Soak for 15 minutes and let gel.
