First, use Melodyne, your ears (if you have good ear-training skills), and/or Mixed in Key to find the key of the music clip. Then, you'll know the notes that should be in the melody to avoid dissonance. Then, use Melodyne (or your ears, see above) to determine the notes in the vocal melody. From there, you have 2 options: (1) transpose the entire vocal melody up or down to match the key of the music, or (2) transpose individual notes to match the key of the music. The first option is probably preferable to keep the melody the same, but if the key of the vocal is off by a large amount (e.g., a 4th), then changing the pitch may make the vocal clip sound odd/bad.
For example, say you analyze the music and determine that it's in Emin, which uses the notes E-F#-G-A-B-C-D-E, the analyze the vocal and find that the notes in the melody are A-Bb-G-A-F-G-C-D-D. That single flat tells me that the vocal was recorded in either the key of Fmaj or Dmin. Since my instrument clip is in Emin, I know that my vocal clip (assuming Dmin) is one full step (two semitones) lower, so I just need to grab all of the blobs in my Melodyne vocal clip and drag them up two semitones and my new vocal melody is now B-C-A-B-G-A-D-E-E. Done.
Using the second option I mentioned above, you could just change a few notes in the melody to match the key of the clip, which will change the over melody. In this case, you'd raise the Bb to a B-natural, and the F-natural to an F#, ending up with the following notes in the vocal melody: A-B-G-A-F#-G-C-D-D. You can try it, but it's probably not going to give you the results you're after.
If you're working with short simple clips, you should get usable results. But, keep in mind that the results may not always be that great, depending on how long and complex the chord changes in the instrument clip are, and how long and complex the vocal melody is. For example, let's say that your instrument clip is playing a single static chord (e.g., Emin), but your vocal clip was recorded over an 8-bar phrase in Amaj and uses the I-IV-ii7-V7 progression (Amaj-Dmaj-Bmin7-Emaj7), the vocal melody may not sound "right" over the instrument clip, even after you transpose the vocals to the right key, which in this case would likely be down one full step to Gmaj (has the same key signature as Emin).
