Lay out the tortillas and spread a tablespoon of cream cheese on each one, leaving a border around the edges.
Divide the smoked salmon evenly among the tortillas, placing it on top of the cream cheese.
Arrange the lettuce, tomato slices, and cucumber slices over the salmon.
Sprinkle the lemon zest evenly over the fillings and season with salt and pepper to taste.
Roll up the tortillas tightly, folding in the sides as you go, to form wraps.
Slice the wraps in half diagonally and serve immediately.
