A little help for a big nose (Mid - Top - Jung)

Hi guys ^^ I'm a silver 4 standard player and i played for the most of the time jungle... But with the current meta i don't like to play tanks so i moved on the midlane. I tried Twisted fate, Ahri , Gp , Yasuo (lol), Kassadin and annie but i just lose my lane and feed... soo this is my question : What champions can i play for learn the mid role? Anyone have some tips and tricks for the midlane?(and a raccomanded champ for start to learn the midlane). And right now for the low elo what jungler can i play for be usefull and do something? (i tried maokai and sejuani but they are too boring). Ty all have a good day ^^ [sg-soraka]
