I think originally alumnae associations formed to assist the collegiate chapters, so perhaps you can help them with a function, ceremony or philanthropic event. Invite alums to cheer on the school's team at Homecoming!

If there's not a chapter nearby, then maybe focus on the spritual/religious aspect of your sorority. Instead of an over-night kind of retreat, you could organize a sorta "mini-retreat". If you have a national advisor on this aspect, then maybe she can help you with the programming.

See if your nationals will give you any support as you try to form a new alumnae association, ranging from development ideas, to alumnae mailing lists, to help with postage.
