Unlike ordinary dirt or grease marks, paint bonds very firmly to glass surfaces. Some paint-removing techniques -- metal scrapers or electric heat guns -- could damage the mirror's delicate surface, but the appropriate paint-stripping chemical will loosen the paint without damaging the mirror beneath. If the dried paint is simply errant drips and spatter from a recent painting project, ordinary nail polish can soften it up for easy removal. But when you're dealing with old dried-on paint, you'll need a more robust solution such as a paint-stripping paste.

Pour a generous amount of fingernail polish remover onto a small portion of a folded or wadded-up paper towel. Rub the wet paper towel onto the paint specks to soften them, then wipe the paint off the mirror.
