I am trying to do a LASSO regression on some data. However, my dependent variable is between 0 and 1. How do I go about this? Do I just apply a sigmoid function to the regression output?
This will surely force the outcome to the 0-1 range, but I am not sure of the technical implications.

Since the response variable is between 0 to 1, i.e., you should perform a beta regression. The package 'gamlss' allows you to do that in addition to fit your model using Lasso.
There are some variations for beta regression. Take a look at the GAMLSS Manual.
