Well it depends on the particular player, but in general with Lisa at a distance you'll want to watch out for the following tools. If you have a response to each of them it'll make things easier on you. The most important thing is patience. Lisa does not have many good tools for opening up a patient player, so once you've got a life lead, don't worry too much about chasing her down.
This is a jumping OH that can catch you if you do strings in the neutral game. If you can bait it out, you can crouch it and throw her for high counter damage. You can also throw her if she whiffs the OH, so be watchful and catch her if the player doesn't space it right.
This is the cartwheel flip you will see a lot of Lisa's doing, it can transition into her carrera stance. However, it leaves her very negative on block, so if she tries anything aggressive after doing this, you can stuff it with a fast mid (46P for Hitomi would work well).
this is a mid drop kick that has a slow startup, but provides a guard break. After this move, Lisa can transition into Carrera and do a high punch, another drop kick, a very unsafe mid punch, or a jumping offensive hold. If you are hit by this move, just be patient and see what the Lisa player does next. If she does the drop kick or offensive hold, you can interrupt them with a quick poke. Or you can just block and the only thing she can do is try to OH (which you can crouch, it is very slow), or do another drop kick. Both the mid and high punch are throw punishable.

this is the backwards belly flop. If it hits you it will guard break you for enough frames for Lisa to get a guaranteed followup. However it is very slow and linear, so if you wait for it and sidestep it you can low throw her once she lands. Be careful because it does retrack a bit.
this is the flying chop, it covers a long distance, but it is very negative. If you can bait it out, you can low throw punish it.
Once you start shutting down these tools, you'll have an easier time walking up to Lisa. If you need more help try to save a replay so I can give you specific advice.
