here is a rough example:

\documentclass{article}

\newcommand{\origref}{}
\let\origref\ref

\newcommand{\splitref}{}
\def\splitref #1:#2\relax{{%
  \def\a{#1}%
  \def\fig{fig}%
  \def\tab{tab}%
  \ifx\a\fig Fig.~\origref{\a:#2}\fi
  \ifx\a\tab Tbl.~\origref{\a:#2}\fi
}}

\def\ref#1{\splitref #1\relax}

\begin{document}
\begin{figure} \caption{foo} \label{fig:foo} \end{figure}
\begin{table}  \caption{bar} \label{tab:bar} \end{table}

In \ref{fig:foo} we see---nothing. Same in \ref{tab:bar}.
\end{document}
