1. Make sure you have a page that gives the details on your affiliate program - ensure the SEO is done to reflect [your topic] affiliate and associate program
2. If your topic is a service, you may consider reaching out to the top websites in the niche and offering them a free trial to try out the program and explain you have an affiliate program available if they're interested. Keep the pitch short and sweet - AKA, get to the point. I get these daily and the shorter it is the more likely they are to get me to reach back if it's an interesting (to me) product or service. After a paragraph, if they don't have the gist laid out, I stop reading.
3. Do competitive intel on your competitors programs - check out their compensation, cookie length, bonus programs, etc and be sure you're on par (and ideally better) than the competition.
4. Do backlink searches to your competitors affiliate creatives - you'd be surprised how many affiliates that will lead you to.
