Preheat oven to 400 degrees F (200 degrees C).
Mix chickpeas, nutritional yeast, olive oil, chili powder, onion powder, and salt together in a bowl until combined. Spread evenly on a rimmed baking sheet.
Bake in the preheated oven, shaking the pan occasionally to re-distribute chickpeas, until crispy, 30 to 40 minutes.
