Place the bacon in a large, deep skillet, and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes.
Drain the bacon slices on a paper towel-lined plate.
Spread the guacamole on 4 slices of toasted bread and the cream cheese on the remaining 4 slices. Arrange a lettuce leaf, tomato slice, and two pieces of bacon on top of 4 slices of bread and top with the remaining slices.
