Prepare the filling by mixing cream cheese, crab meat, green onions, soy sauce, and garlic powder in a bowl.
Lay out the wonton wrappers on a clean surface and spoon a tablespoon of the filling onto the center of each wrapper.
Moisten the edges of each wrapper with water, then fold them over to create a tight seal, forming a triangle or a pouch.
Heat oil in a deep frying pan over medium-high heat. Test the oil temperature by dropping a small piece of wonton wrapper into the oil.
Fry the crab rangoon bombs in batches, ensuring they don't overcrowd the pan, until golden brown on all sides.
Remove the bombs from the oil and drain on paper towels to remove excess oil, then serve immediately.
