This manga is usually in 関西弁 but i think i cannot finally understand that little sentence very well

The same sentence in standard Japanese, with nothing omitted, would be:
屁をしようと思ったら、漏れた(よ)。
I tried to fart, and then [it] leaked (i.e., I ended up sharting).
- を has been omitted
- しよう has been contracted to しよ
- と has been omitted
- 思ったら has been contracted to 思たら
