I found are datasheet reference at https://www.cree.com/led-components/media/documents/data-sheet-JSeries-5630.pdf
Page 27 has the recommended dimensions for the solder pads. With that, and one of the old white SMD leds, I created a new part.

Took longer than expected because I also played around tweaking the breadboard and schematic views.
