In the Cloudflare dashboard, you create an A record in your domain's Zone that points to the IP address of your VPS. In the Dashboard, find your Zone (should be your domain name), click on it, click DNS. Create a new record if you don't have one already, and select "A" as the type. Enter the IP address of your VPS. I like to leave this proxied (i.e., leave the little cloud orange if it doesn't cause issues). Note that doing it this way means your top-level domain will only point to your VPS, which your reverse proxy should be set up to catch and redirect over your VPN tunnel back to your server at your home. Seems a bit indirect, but should work alright if you don't mind the extra latency.

With this setup, you wouldn't be able to run any other services on your domain. You'd have to set things up differently (your reverse proxy config would need the most alteration). Cloudflare is pretty simple on the DNS front.
