Just import the pipe operator, by adding a line like

importFrom(magrittr, "%>%")

in your NAMESPACE file, or if you're using roxygen2, putting

#' @importFrom magrittr %>%

into one of your .R files to do the same thing.

You may or may not want to export it as well. Do export it with a line like

export("%>%")

in your NAMESPACE file or with roxygen2

#' @export
magrittr::`%>%`

if you want your users to use the pipe operator when they are using your package. Don't export it if you only need it to be available internally.
