As above, if you didn't make a backup of the seeds/QR codes when adding them to Authenticator (they all tell you to do this) you will need to contact the exchanges and find out from each one what their policy on restoring access to your accounts is.
Make sure that when you are setting up Authenticator again that you back up the seeds/QR codes.
FWIW, I am not a fan of the authenticator apps which back up the codes to the cloud - it just seems like another potential weak point. I believe Coinbase recommended that people move away from Authy for this reason.

Yes, this is so annoying. Lose the unit with the Google Auth and you are in trouble if you have not made a backed up the codes. I have Google Auth on my phone and on my iPad. That way if one dies I will have the other.
I use Googles 2FA, and always take a picture of backup code when i enable 2FA. I then store the pictures on a USB. Works fine and would be fine in a situation like yours when you lose the phon :/
Don't use Google Authenticator. You can't easily backup your 2FA with it, and if you lose your device, recovering each of your accounts is a pain in the ass.
Instead, use a 2FA app that let's you backup your codes. I recommend andOTP:

andOTP is a free and open source 2FA app for Android that lets you backup and restore your 2FA codes whenever you want.
This means that unlike Google Authenticator, if you lose your phone or need to reset it, your 2FA codes can be restored and your accouns will be safe.

You need backup code for given exchange (you were provided with before you enabled the 2fa) ... this is what i'm sure about
or
you need to restore the entire google 2fa account (like you would move your your 2fa app to another device ) for this there are some security backup codes provided by google itself ... in this i'm not so sure. Try to investigate (will appreciate if you report back in case you succeed)

If you don't have any backup key i think its impossible to recover your google 2fa..
Better to contact the exchanges and tell them that your phone was lose and you don\t have any backup key to recover your 2fa. .
I think they will ask for other proof that you own the account from exchanges like verifying identity..

Hi,
Lost my phone with google Two Factor Authenticator on it that I needed to log into some exchanges. Because it was lost I remotely factory reset/deleted the device and then removed the device from my google account for security. After this I bought a new phone and downloaded this google 2FA app again. Cannot see the codes now which I need to log onto those exchanges. What shall I do?
