This isn't as "glamorous" as Neils method involving lots of mdadm commands, shrinks and grows, but sometimes it's good to keep things at a simpler level?
Another way would be to add the new raid1 with missing drive to the lv, and pvmove all extents off of the existing raid5 md pv, then vgreduce away from it, stop the raid5, zero-superblock, and add one drive to add redundancy for the raid1.
But that has little to do with linux raid, and all to do with LVM. It also means you can do everything online since pvmove doesn't require to offline anything.
