This looks like your block range must have been off. Try using the suggested parameters for the last round and a 1000 and try again:

 tx, err := transaction.MakePaymentTxn(fromAddr, toAddr, 1000, 200000, txParams.LastRound, (txParams.LastRound + 1000), nil, "", genID, genHash)

Also your fee is going to be too low. I think the minimum is 1000 microalgos.

Also, it might be better to use SuggestedParams() in order to get the suggested fee dynamically (if you agree on a reasonable weighted average calculation).
