You can use the same kind of anchors. I hung a t.v. at my cousins house above a fireplace with the same anchors. If you were in town, I'd be more than happy to help you hang it and run the wiring. The only thing is, when you drill for the anchor holes, go one size smaller than what is suggests for that anchor size. The reason being is that the kind of brick you have is softer that cement brick, that way you can hammer the anchor in, and it will be a lot stronger that way.
