The Draytek modem automatically deals with PPPoE to PPPoA conversion. It should be totally plug and play. Any settings that need changing would only usually need changing on the USG.
Before you do anything else, can you confirm you've changed your WAN port on the USG to PPPoE, and that you've entered your ISP credentials into the USG.
It should just work. If it doesn't, I have a likely explanation.
I am 100% certain you are wrong about the default IP address of the Draytek.
The Vigor 130 comes from the factory on 192.168.2.1, not 192.168.1.1, so you may have a problem in that you have the same network as your USG which it might not like.
To fix this, you'll need to connect the Vigor 130 directly to a laptop.
Whilst you're doing this, check the other settings are correct for your ISP (VLAN ID etc). I repeat the point I made earlier - that you do not put your ISP credentials into the Draytek. They go into the USG, and you need to change the USG to use PPPoE on the WAN port.
You can get these settings off your old router, but unless your ISP is weird, you will want the VDSL VLAN tag setting to 101 (which is the Draytek default in the UK).
I've never seen a Vigor 130 not work as soon as it is connected though. As long as the USG is correctly configured, everything should be fine. I have concerns about the IP range though.
Incidentally, if you want to test the Vigor 130 directly connected to a laptop, the same as above applies. You need to add a PPPoE interface. On a Mac, go into the network settings page, hit +, choose PPPoE, then choose 'Ethernet' from the list of interfaces Next, fill in the 'Account name' and 'Password' (Leave service name blank). Tick the 'show PPPoE status on menu bar'. Click 'Connect' and watch what happens on the menu bar.
So just to clarify the fundamental difference between using something like a Vigor130 and a router is that the device that is connected to it is the one that initiates the connection. So that's why the credentials go into the USG or the laptop if you have one directly connected.
If you've fiddled with any of the settings in the Draytek, I suggest you do a factory reset on it and start again as all the factory settings are sane for pretty much any standard use case in the UK.
