In a large bowl, mix whole wheat flour, all-purpose flour, brown sugar, baking powder, and salt.
In a small bowl, mix oats and soy milk. Whisk in eggs and olive oil. Pour into the flour mixture all at once. Continue mixing until smooth. Gently fold in blueberries.
Pour batter about 1/4 cup at a time onto the prepared griddle. Cook 1 to 2 minutes, until bubbly. Flip, and continue cooking until lightly browned.
