Cook tortellini according to package directions, but reduce cooking time by 2 minutes. Drain and let cool slightly.
In a shallow bowl, mix breadcrumbs, Parmesan cheese, garlic powder, and Italian seasoning.
In another bowl, beat the eggs.
Dip each tortellini into the egg mixture, then coat in the breadcrumb mixture, pressing gently to adhere.
Heat oil in a deep skillet over medium heat. Fry tortellini in batches until golden brown and crispy, about 2-3 minutes per side.
Remove with a slotted spoon and drain on paper towels.
Serve warm with marinara sauce for dipping.
