In this article you will see how to configure your device to become a Wi-Fi extender/repeater/bridge. Instead of relayd it should be possible to use kmod-trelay, the only information about using it can be seen in its source code, if you used it successfully please add a section for it in this article. Currently it seems to be the hardware/SOC limitation (related to MAC cloning?) The most common problem is that the client router cannot pass the DHCP message between the main router and the client connected to the client router. Using relayd as instructed in this article isn't guaranteed to work with all Openwrt compatible devices or wifi networks.

If supported by both devices, consider using WDS, Layer 2 GRE tunnels (“gretap”), or mesh networking.
