What level spellcaster would the cleric be? Matthias is on a good path here. The things that come to mind involve spider-like concepts of entangling, poisoning, and darkness. Maybe even summoning spiders as an ability.
I would suggest that if your priest is powerful, she should be female, as is the case with spiders and in Drow culture.
In the books, many of the clerics rely heavily on controlling magic. As suggested, anything you could relate to a spider theme would be good. Faerie fire is an excellent choice as it negates penalties that other Drow might use to buff themselves defensively. This fits with the back-stabbing and distrustful society that the Drow favor.
I'm trying to create a monster and I could use some help finding good spells to use!
Well, web is obvious. Other than that, the best advice I can offer is to look at the various drow that already have stat blocks.

The circle of underdark Druid spell list might also provide some ideas.
One thing that I haven't seen here yet is to just reskin-
Spiritual weapon: Ethereal spider, maybe?
Toll The Dead: Instead of bells, perhaps squeals and screams of spiders like Shelob in Lord of the Rings movies?

Conjure Animals maybe? With RAW they could summon 8 Giant Wolf Spider or 2 Giant Spider.
