Let is charge for a few hours then try powering on by holding power button until you see the boot screen. Hopefully that gets you booted.

If you are rooted with an unlocked bootloader, you may be hard bricked. In that case, you will need to buy a jig from somewhere like eBay or scour the internet for fixes for this. I am a couple of months late with this reply but hopefully you will have sorted this issue out by now.
