Preheat oven to 350 degrees. Line a baking sheet with parchment paper and set aside.

Combine whole wheat flour, oat flour, baking powder, baking soda, salt, chia seeds, and organic cane sugar in a bowl. Mix in coconut oil in until the mixture is crumbly. Stir in soy milk, 2 tablespoons lemon juice, and 2 tablespoons lemon zest until a dough forms. (add an extra tablespoon or two of soy milk if needed)

Transfer dough to a bowl and knead. Gently roll into a ball and turn out onto a lightly floured surface. Press into a circle about 1 inch thick; cut into 10 wedges. Place scones onto prepared baking sheet.

Bake in preheated oven until edges are lightly golden brown, 18 to 20 minutes.

Mix confectioners' sugar, 1½ tablespoon lemon juice, and 1 tablespoon lemon zest in a small bowl. Drizzle or spread frosting on top of scones while still warm.
