Preheat oven to 350 degrees. Grease loaf pan with butter, shortening or cooking spray and set aside.

In a large bowl, stir the yogurt, brown sugar, pumpkin pie spice, cinnamon, banana, vanilla and pumpkin puree until well combined. Add eggs, beating well after each addition.

In a separate bowl, stir together flours, salt, and baking powder. Add to the wet ingredients. Stir until combined. Add chocolate chips, reserving a few to place on top of the loaf.

Pour into a greased loaf pan, gently press the reserved chocolate chips into the top of the loaf. This is totally optional. I just think it looks nice.

Bake at 350 for 45-50 minutes, until golden on top and a pic inserted into the center comes out clean.
