Since the original sed command took "Haskell" as standard input, why not:

  {-# LANGUAGE OverloadedStrings #-}

  import qualified Data.Text as T
  import qualified Data.Text.IO as T

  main :: IO ()
  main = T.interact (T.replace "k" "sk" . T.replace "ke" "-ki")

Looks good to me, even as a Haskell ignoramus. I had tried it long back, but found it tough at the time.

What is the reason for hiding the putStrLn of Prelude and importing that of Data.Text.IO?
