In a small bowl, mix flax meal with water. Let sit while preparing other ingredients.
Preheat the oven to 350 F/180C. Grease an 8 inch round pan. In a large bowl combine flour, brown sugar, baking soda, salt, ginger, cinnamon, and mace. Drain the berries, reserving the juices. In another bowl, combine the tofu and the blueberry juices. Add the melted margarine, flax mixture, and maple syrup. Add 1/2 cup flour mixture and beat until smooth. Add the rest of the flour mixture and beat until smooth and fluffy, about one minute.
Spread 2/3 of the batter in the pan. Arrange the blueberries over the top. Spoon in the remaining batter without completely covering the berries. Bake for 40-45 minutes, or until the top is dry and springy and a tester comes out clean.
