A few strategies to help your vocal track stand out in your mix are saturation for warmth, compression to control dynamics, and EQ to boost your high-mid and high frequencies. You can also double up and pan your vocal track in different ways to give it more presence in the mix.  For example, you could take your vocal track and make four copies. Next, leave two vocal tracks down the middle and pan the other two left and right. This will really help your vocals stand out in a busy mix.
