EFI partition deleted

Hello everyone!
So I did somethings really stupid :), after removing my hdd and putting it back the system couldn't find neither my windows or kali bootloader, I had a kali installation media on my thumbdrive so I plugged it in and when rebooting I somehow got into my windows so I followed some instruction on YouTube to fix the windows bootloader and then afterward tackle the kali linux problem, but in the process I accidentally applied the instructions on the kali efi partition instead of the windows one. I downloaded the kali linux live media and wanted to format the efi partition to make a new one but I don't know which file system type I should use (xfat,ext,fat32) or how to make the efi partition again and install the grub... so please help me guys I'm desperate. I need my for studies :') and thanks in advance.
