In a heavy-bottomed pot or dutch oven, heat about 2 inches of vegetable oil to 350F over medium high heat.
In a bowl, mix together the cream cheese, crab meat, green onions, Worcestershire sauce, soy sauce, and garlic powder.
Place about a teaspoon of filling in the center of the wonton wrappers.
Brush water around the edges of the wrapper, then bring the corners of the wonton wrapper together in the center and pinch to seal the filling inside.
Carefully add the rangoons into the oil and fry until golden brown. Drain on paper towels, and serve with sweet and sour sauce if desired
