Preheat the oven to 400°F. Spray the baking (or muffin) pan with cooking spray and set aside.
In a large bowl, whisk together the cornmeal, flour, sugar, baking powder, baking soda, salt.
In a separate bowl, whisk together the soy milk, eggs, oil.
Stir the wet mixture into the dry mixture, until thoroughly combined.
Pour the combined mixture into the baking or muffin pan. Bake until golden brown, and until a toothpick inserted into the middle comes out clean- about 25 to 30 minutes.
