It has a single Dexter Torflex Alex 4inch 4 bolt brake flanges are already attached from the factory, 15inch wheels w/ 5 x 4 1/2 lugs and spacing, can you recommend the parts that I would need.

A good starting point for your project to add electric drum brakes to your trailer is a review of the linked article which covers this process in detail. You will need to select brakes based on the weight rating of the axle on your trailer, which should be indicated on a sticker or plate, and you'll need to select new hub/drum assemblies that use the same bearings as the hubs currently on your trailer. This will ensure compatibility of the new hub/drum assemblies with your spindles. If you cannot find part numbers you can measure the spindles using a digital caliper like # PTW80157 at the points where the bearings ride.
The linked photo shows the typical location and appearance of the bearing and seal numbers on those parts. It also shows where to measure your spindles in the event you cannot obtain the bearing and seal numbers.
The link provided will take you to our page for all hub/drum assemblies for your wheels with a 5-on-4-1/2-inch bolt pattern. All of the available units are rated for 3500-lb axles and all happen to use bearings # L68149 and # L44649. I recommend # AKHD-545-35-K. It can be used with etrailer.com self adjust electric brake assemblies # AKEBRK-35L-SA (left) and # AKEBRK-35L-SA (right).
You will also need to wire your trailer for brakes by replacing the 4-pole with a 7-way plug like # H20046 from Hopkins. You might use a junction box like # 38656 to make those connections. The article will help you with the other components required, including a breakaway kit like # 20020.
