I'm not exactly sure what you're doing. But the "trick" to doing most of
this in a chroot is to bind mount /dev, /proc, /sys and /run into the
chroot.

Then things like installing the kernel, building the initrd etc
(usually) just work.

"Add changes to UEFI to start booting" depends on the actual hardware
that will boot. If you're preparing images on one system to boot on
another then that bit you'll have to solve by booting the hardware.

I'd probably pick a live distro but it's theoretically[1] possible to
generate your own bootx64.efi that will then boot your system. Once it's
booted you can then use the normal tools to replace it with a more
easily maintained debian solution.

[1] Not just theoretical, I've actually done it once long ago.
