We're at the same point. We just finished paying down all our debt a few months ago, then we took a couple months to re-build our emergency fund. Now we have two big goals of saving 50K+ for a down payment and saving for eventual retirement, which is probably multiple decades away. Now that the numbers are bigger and the end results more nebulous, it's much harder to find that daily inspiration to stay frugal! Something I did recently to try and inspire us was taking our big giant retirement number and dividing it by two, dividing again, and again, down to a number that we currently have. I made the next number in sequence our next Big Goal. I'm hoping we can plan a celebration of sorts when we get there, and record how long it takes to reach each milestone. This is all with the hope of watching compound interest do it's magic in a more tangible way, as well as increasing our savings as we get "close" to each goal benchmark.
As for the down payment, it's a smaller number so it's slightly more tangible. But it's still a good three years away, so it will be hard to keep motivation up. I'm planning to keep track of the percentage we save each month (in both retirement contributions and house savings) to keep an eye on things and maybe spur us to do better over time. It's hard to do much more when all the "low hanging fruit" of cost cutting has been picked.
The nice thing about getting rid of debt is that you can justify loosening the purse strings a tiny bit. As long as you have an FI date you're comfortable with, let yourself do things that were out of reach when your hair was on fire. Taking a small trip that you wouldn't have considered during debt payoff may be a good motivation to save, even though it's not contributing directly to your FI goal.
