I grew up fishing an oxbow lake for LMB. Redfish are a lot like LMB. They both are found around structure. I don't know where you plan on going, but reds are often near oyster reefs, grassy shorelines, marsh drains. Lots of ways to fish for them. Bouncing off the bottom a 1/16 oz or 1/8 oz jig head primed with a paddle tail is a favorite. Lots of topwaters work. So do spinners, spoons, wake baits, flies. Most marshes are pretty reliable this time of year.
Same line, reel, Rod you used for LMB ought to work for reds. Kayaks are good to get into redfish country, but you can find them in wade in areas too. Find some points, coves, wind blown shorelines. High water sends many way up in the grass. Fish shell near the grass if the water is really high. Low water sometimes concentrates them in guts and drains. Lots of peopke like gulp under a popping cork. Pop, wait, repeat.
