The SSH credentials will be whatever you set in your preseed file. Without looking at your template I don't know what the sticking point is, but here's a basic guide on what your preseed file needs to contain for Packer to connect.

Given that your username/password is centos centos you may need to set "d-i user-setup/allow-password-weak" in your preseed since that's not a strong password. Try to manually SSH into your instance using that username/password combo during the time Packer is trying to connect. Does it work? If not, set "headless": false in your Packer template and see where the preseed is getting stuck.
