In a large bowl, mix the flours, brown sugar, baking powder, baking soda, salt, and spices.
In a blender, mix the margarine, pumpkin, soy milk, flax egg, and vanilla and blend to combine well.
Pour the wet ingredients into the dry mixture and stir together with a wooden spoon to form a soft dough. On a lightly floured surface, knead the dough briefly until it just comes together.
Cut the dough into 7 large or 14 small pieces, shape them into whatever scone shapes you like (circles, triangles, random shapes) and arrange them on a parchment-lined baking sheet.
Bake at 400F for 10-12 minutes, until they’re browned on the bottom and a toothpick inserted into the middle of a scone comes out clean. Cool on a wire rack and enjoy warm.
