I’ve started my first batch of wine using the toasted oak chips, added after the primary fermentation. I am wondering if during the racking process about to be done after the secondary fermentation, do I transfer the oak chips too?

Adding oak chips, that have been sap cleared and toasted, directly to the wine has long been one of the tricks up the home winemaker’s sleeve. It allows you to enjoy all the advantages of barrel-aging your wine without the cost or work of using and actual wine barrel.
These toasted oak chips are made from white oak that has been kilned to sap clear and then toasted to raise the woods sweetness to the outer surface of the chip. This toasting is no different than what is done to the inside of a wine barrel.
Typically, we recommend adding oak chips after the fermentation has completed and the wine has cleared. The wine is bulk-aged in something like a carboy along with the oak chips for a matter of weeks to months. You can sample the wine along the way to determine when you would like to take the chips out.
Adding the oak chips during the primary fermentation is okay, however you do not have as much control over the flavor when using this method. It’s hard to know if the wine needs more time on the chips or not. This is because you do not know what the wine is going to taste like at that point in the process.
The only exception to this argument is when you are making wine with a wine ingredient kit. Normally, these kits will instruct you to put the oak chips in the primary fermentation, just as you have done, and then remove them when racking the wine into a secondary fermenter. This method is okay in this situation because the producers of these wine ingredient kits already know exactly how much oak chip is needed in the primary fermentation to end up with a wine in good balance. They have already determined this by bench-testing several batches with varying quantities of oak.
If you are not making a wine from a wine ingredient kit, then I would suggest taking the toasted oak chips out of the wine must at this point. You may already have more oak impression in the wine than you like. You have no way of knowing with a wine in progress. Once the fermentation has completed and the wine has cleared, then you can revisit the possibility of adding toasted oak chips at that time for further aging.
