Pat the shrimp dry with paper towels.
In a bowl, whisk together the eggs, hot sauce, and mustard.
In a separate bowl, mix the flour, cornstarch, salt, black pepper, paprika, oregano, garlic powder, and taco seasoning.
Dip each shrimp into the egg mixture, then coat it well in the seasoned flour mixture.
Heat oil in a deep skillet or frying pan over medium heat.
Fry the shrimp in batches until golden brown, crispy, and cooked through.
Remove and drain on a paper towel-lined plate.
Serve hot with cocktail sauce, tartar sauce, ranch dressing, or spicy mayo.
