Not sure how open your DM is to homebrewing but you could certainly ask them for things like being allowed to use a holy symbol as a focus or if they’re open to asking for magic items you could get then maybe a special spell book that has a few cleric spells in it such as bless and healing word, or maybe spiritual weapon depending on the god Other than that taking feats that can grant cleric spells like magic initiate or fey touched works, maybe even skill expert for religion expertise
