don't play for your adc if you know they can't carry, try to focus on counter ganking or making plays midlane everytime you back or shove the wave
since you're playing pyke take bush control, deward and look for hooks out of vision

Regardless of who you play, I think the main thing you can do is identify the carry (and it could be you too btw and that's ok) and set THEM up. Because your ad might be a god, and they might also be a dog. Just get enough farm to get your core items and feel free to roam and influence other lanes.
