I use gl.inet routers on both devices, but other brands probably do ok as well. The VPN software is pre-installed on their devices. I prefer using Wireguard however both OpenVPN and Wireguard are there. On the routers, you create public and private keys but you only share the public keys between them. You can also create a QR code public key which you can scan with your phone or laptop. Use the standard Wireguard app for your phone. The default key setup will make your clients appear to be in the LAN at home whenever you enable the VPN.
