Whisk together all of the marinade ingredients.
Slice the tofu into 8 slabs (cut in quarters length-wise, then cut each quarter in half - see pictures for example) and submerge them in the marinade. Cover and let the tofu marinade for at least one hour OR overnight in the fridge.
When you're ready to bake your tofu, preheat the oven to 400 degrees. Line a baking tray with parchment paper. Place the tofu on the baking tray, with some space between each piece so they aren’t touching. Reserve the marinade. Place tofu in the oven and bake for 15 minutes.
While the tofu is baking, pour the reserved marinade into a small saucepan. Heat over over medium heat and simmer until it's reduced by two thirds. It will be thick and syrupy when it's ready.
Once the tofu has baked for 15 minutes, baste the top and sides of the tofu with the reduced sauce. Flip the tofu and baste the other side. Return the tofu to the oven and bake for another 10 minutes. Then remove from the oven and baste, flip again, and baste. Bake for another 10 minutes. (Total cooking time of 35 minutes). Serve with the extra sauce poured on top or as is.
