Well I'd draw on examples from witch craft. Otherwise, I'd suggest to use things that relate to their descriptions. Like Madris Orundi is a dancer, who is a muse for artists, the creative types and lovers. She's a match maker... So maybe things like dancing shoes with red ribbon tied together, or a mirror, a flower that represents love (like a rose), the colour red (which represents love). If she's a match maker I'd suggest acting like a cheerful, happy middle aged woman who wants to help young lovers find their perfect match?
I could write up a list of magic things and sort of based on things like luck,love,protection, etc. Most things from stones to colours, flowers and items have magical meanings. Dark tales and disturbing legends, which is a source book for the voodan class may have some tidbits on ideas, and possible the gazetteer about sourange maybe as well. It's been a long time since I've read those ones
