It's different for each medium. In visual media, a lot of it is in the music, lighting, sound effects, etc. In literature, it's vividness of description and, often, intentional Purple Prose.
But in both cases, the keys seem to be exaggeration and humorous substitution (i.e.: using tropes that would normally be found in a much more dramatic scene in a mundane one.)
For example, if you were trying to make copying a spreadsheet epic, you could have the character slam the copier shut so hard it emits a shockwave that blows peoples' clothes off, yell "Finger of the burning dragon!" when he hits the start button, then make the glow from under the lid so bright that it can boil your eye fluids at close range.
I think you'd have to be more specific about what you're trying to pull off, though.

Project progress: The Adroan (102k words), The Pigeon Witch, (40k). Done but in need of reworking: Yume Hime, (50k)Workplace and domestic settings. Two people who live and work together.
Have them argue in a manner more befitting superheroes/supervillains than housemates.
"FOOLISH WRETCH! Mr. clean is as nothing compared to the cleansing force of PINE FRESH!"
Likewise, giving everything vaugley important origins as elaborate as this desk.

What makes Mundane Made Awesome work? I've noticed it's a recurring theme in a lot of works that I enjoy, and I'm trying to figure out how to make a good Mundane Made Awesome story arc.
