Record your vocal track without any processing if possible. A "raw" vocal track will give you more options later for incorporating it into the mix. Record the rest of your tracks as normal. Once complete, you are ready to mix your music.
Use the EQ to get rid of unnecessary "noise" in the vocal track. Almost as a rule, audio engineers will "cut" all frequencies below approximately 75Hz in order to "lighten" the vocals and prevent the bass rumble at those frequencies from clogging the overall mix.
Use the EQ to boost the frequency ranges that will enhance the voice. Experiment in particular with boosting the 150-250Hz range until the vocals take on an increased strength or "presence." This is a matter of taste, but you are most likely to find your preferred "sweet spot" within that frequency range. Try boosting higher-frequency ranges -- 3kHz and above -- slightly as well to see if they further enhance the vocal track's presence.
Apply compression to your vocal track. Vocalists rarely maintain a consistent volume on a raw recording. A compressor will increase the volume of the quieter parts while lowering the volume of louder parts, making the overall volume of your vocal track more consistent. This will help to bring your vocal track "forward" in the mix because it allows for greater control over its overall gain and volume level relative to other tracks.
"Layer" your vocal track. In other words, produce two more copies of your post-EQ, post-compression vocal track and give them tracks of their own using your mixing equipment of choice (software or hardware). Use panning to widen the "space" your vocals occupy in the mix by panning one layer left and another to the right, keeping at least one in the middle of the panning range. Experiment with different panning "spaces" until you find one that gives your vocals the dominance over the mix that you desire.
Apply any effects you might want to use to your vocal track. For example, reverb, phasing, pitch correction, distortion and different kinds of filtering all lend their own unique character to the sound. Beyond the basic steps described above, mixing is a matter of creative taste, so experimentation is key.
