I took this recipe and basically used a chia gel substitute in stead of the 4 eggs, and used vegan butter and nut milk (almond) instead of the buttermilk and milk ingredients.
Turned out great!
Chia Gel (egg substitute)
* 2 tablespoon chia seeds (I used ground up seeds)
* 1/2 cup of cold water
Combine cold water and chia seeds in a bowl and allow to sit
