Heat oven to 400F. Spray sheet pan with cooking spray and set aside.
In a large bowl, add all the ingredients for marinade and whisk well to combine into a smooth liquid. Break tofu into large chunks and marinade. Using a spatula, gently fold until all the tofu is coated in the marinade. Set aside to rest for 10 minutes.
In another medium bowl, combine panko and cornstarch.
Working in batches, place marinated tofu into the panko and cornstarch mix. Coat each piece and place onto the prepared sheet pan. Repeat until all the tofu pieces are coated.
Spray cooking spray on the coated tofu. Bake in the preheated oven for 20-25 minutes until golden brown.
