Preheat oven to 350º F.Very lightly grease a baking sheet with cooking oil.
Drain the chickpeas and transfer them to a clean kitchen towel or a few paper towels. Gently pat them dry. The dryer they are, the better.
Transfer them to a medium-sized bowl. Add the oil, hot sauce, chili powder, chipotle chili powder, cumin, and garlic salt; stir until evenly coated.
Transfer them to the prepared baking sheet in an even layer and bake them, shaking the pan halfway through baking time, until the chickpeas are crunchy. This will take about 50 minutes to 1 hour.
Once ready, let them cool for at least one hour. The chickpeas will get crunchier as they cool.
