Whisk the soy milk, sugar, vanilla and maple syrup in a large bowl.
Gently mix in the bread cubes and leave the mixture to sit for 10 minutes, to allow the bread to absorb the soy milk and become soft.
Gently mix in the raisins and cinnamon and pour the mixture into the well greased 8×8 pan.
Place the pan in a preheated oven and bake for 30 to 45 minutes or until the pudding turns golden brown and there is no milk.
