In a medium mixing bowl, combine the softened cream cheese, smoked salmon, lemon juice, capers, dill, Worcestershire sauce, and garlic powder.
Using a hand mixer or a fork, blend the ingredients together until smooth and well combined.
Taste the mixture and season with salt and pepper as needed. If using, fold in the chopped green onions.
Transfer the dip to a serving bowl and cover with plastic wrap. Refrigerate for at least 30 minutes to allow the flavors to meld.
Serve chilled with crackers, pita chips, or fresh vegetables.
