In a medium mixing bowl, combine the softened cream cheese, smoked salmon, lemon juice, capers, dill, Worcestershire sauce, garlic powder, and onion powder.
Using a hand mixer or a fork, blend the ingredients together until well combined and creamy.
Taste the mixture and season with salt and pepper as desired.
Transfer the dip to a serving bowl and cover with plastic wrap. Chill in the refrigerator for at least 30 minutes to allow the flavors to meld.
Before serving, garnish with sliced green onions. Serve with assorted crackers or vegetable sticks.
