Lay out all slices of bread on a clean surface. Spread a thin layer of softened cream cheese evenly over each slice using a butter knife, reaching the edges.
In a small mixing bowl, combine the remaining cream cheese, lemon zest, and chopped dill. Mix until smooth and well incorporated.

Spread a thin layer of the dill-cream cheese mixture over half of the bread slices. On the other half, layer slices of smoked salmon evenly.

Place the slices with the salmon on top of the spread slices, aligning edges to create sandwich layers. Gently press to seal the fillings inside.
Use a serrated knife to carefully cut each sandwich into small, even rectangles or triangles. Chill the assembled sandwiches covered in plastic wrap for at least 1 hour to set.
Just before serving, arrange the chilled sandwiches on a platter. Optionally, garnish with additional dill or lemon zest for presentation.
