In a large mixing bowl, add the tofu chunks, dairy free yogurt, garam masala, cayenne, ginger, garlic, salt and lemon juice. Stir gently and make sure every piece is covered. Put in the fridge and let it marinate while we get our masala sauce together. This tastes best if it's had at least 30 minutes to marinate.
1 cup unsweetened and plain dairy free yogurt, ¼ teaspoon cayenne pepper, ¼ teaspoon turmeric, 2 teaspoons garam masala, ½ teaspoon salt, 1 tablespoon lemon juice, 2 cloves garlic, ½ inch fresh ginger, 2 (16 oz) packages of extra firm tofu
