A good way to go about this is to create a spreadsheet, find niche related resources that you could possibly get a link on. Directories, Blogs, Related Websites, Guest Post Areas, etc. Organize them, than once you have a good list built, go after the links using common practices, calling, emails, social areas like Facebook and Twitter.
Once you've gone through the list you've created, target a new area in your link building campaign, and start the process over. Just keeps things a bit more organized
