By now most DAWs have a native harmonizing/pitch shifting plugin but what you probably want is "smart" one that can constrain your shifted note(s) to a chosen scale or, even better, use the info from the chords in an instrumental track to constrain the notes as you go along. Even better: both of the previous options. Waves, Melda, Eventide and iZotope, among others, and Melodyne, as Mario mentioned, all have offerings along these lines (sometimes more than one). You're going to have to check out what features intrigue you and satisfy your needs and workflow. Indeed, there is magic available for you. Hopefully, some one else will chime in with their familiarity and experiences with this type of plugin.
