Cut tofu into 1-inch cubes.
Whisk tamari, maple syrup, rice vinegar, sesame oil and red pepper flakes in a small bowl.
Heat avocado oil in a large skillet over medium-high.
When oil is hot, add tofu slowly (cautious to not get splattered with oil).
Cook tofu until very crisp, about 5-6 minutes.
When tofu is done, remove and set aside in a bowl.
Reduce the skillet to medium heat and add the sauce.
Cook until the sauce is thick, about 4 minutes.
Remove sauce from the stove and pour it into a glass dish.
Divide the tofu on plates and drizzle the sauce over each serving.
Serve with noodles, scallions, and fresh herbs.
