Split the bagel and toast the cut sides until lightly golden and crisp, about 2–3 minutes. Place both halves cut-side up.
Spread the 2 tablespoons of cream cheese evenly over both toasted bagel halves.
Arrange the 3 ounces of cold-smoked salmon in soft folds over the cream cheese. Keep the salmon refrigerated until you're ready to assemble.
Top with drained capers, thinly sliced red onion, and fresh dill. Add black pepper and squeeze lemon over the top if desired. Serve immediately while the bagel is crisp.
