Slice tofu width-wise into 6 slabs. Use a kitchen towel to gently press each slice to remove excess liquid; cut into 1-inch cubes.

Combine hoisin, soy sauce, chili garlic sauce, and vinegar in a small bowl; stir with a whisk.

Heat oil in a large nonstick skillet over medium-high. Add tofu and cook, untouched, for 3 minutes, until bottom of cubes are golden-brown. Toss and cook 5 extra minutes, tossing occasionally, to brown all sides. Add Asian glaze and cook 2 more minutes, stirring often, until tofu absorbs glaze and becomes caramelized. Remove from heat and serve.
