Not sure how you do it in LUCI as I haven't used the GUI in a long time... but from command line just login and edit /etc/config/dhcp to add a block like this:

config host
        option ip '192.168.1.5'
       option mac 'xx:xx:xx:xx:xx:xx'
       option name 'SomethingMemorableForYou'

Update: In LUCI go to "Network -> DHCP and DNS" then scroll way to the bottom and find the section that says "Static leases". Hit add, fill in your info, and apply.
