Toss until well combined. Place on a baking sheet lined with parchment paper.
Bake for 25-30 minutes or until golden brown and crispy.
Meanwhile, whisk together all sauce ingredients in a small pot.
Bring to a boil, then lower the heat and let simmer until thick, whisking regularly.

When the tofu is done, remove from the oven and let cool for 5 minutes.
