Last week I followed this recipe from Happy Herbivore to make scones using banana instead of shortening, also adding 1 Tbs sugar, 1/2 cup raisins and 1tsp cinnamon. They were so, so good:
Whisk 1 cup white whole wheat flour, 2 tsp baking powder, 1/2 baking soda (you can leave this out), pinch salt. 1/2 to 1 banana (more banana, more banana flavor), 1/3 c soy milk, perhaps a splash more, until its wet and thick. Drop spoonfuls on a greased cookie sheet (or line with parchment paper) and bake about 10-12 mins 400F, or until firm and golden at the edges.The key to biscuits, regular or low fat, is to mix them as little as possible.
