I'm guessing you're new to DF:LW. The mods you ask of in this game are just called custom maps. There aren't really a whole lot of altered items like in Rainbow 6 or the like. If you're looking for these custom made maps, you can find them here or other sites in the links section. For off-line play, you'll need to d/l SP/Co-op maps as any other type won't have any AI in them.
